Introduction

In this tutorial we learn how to install blktrace on Fedora 34.

What is blktrace

blktrace is a block layer IO tracing mechanism which provides detailed information about request queue operations to user space. This package includes both blktrace, a utility which gathers event traces from the kernel; and blkparse, a utility which formats trace data collected by blktrace. You should install the blktrace package if you need to gather detailed information about IO patterns.

We can use yum or dnf to install blktrace on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install blktrace.
